A Method to Increase the Minimum Distance of Turbo Codes with Weich-Costas Interleaver

摘要

A method to increase the minimum distance for turbo codes with Welch-Costas interleavers is proposed. The minimum distance obtained by the proposed method is comparable to that corresponding to the S-random interleaver [1]. A slight increase of memory is required compared to the classic Welch-Costas interleaver [2].
